Abstract (en)
[origin: US2014116175A1] An auxiliary hydraulic pressurization system for use with a vehicle including a transmission having a hydraulic reservoir, a hydraulic circuit, and a main pump is disclosed herein. The auxiliary hydraulic pressurization system includes an auxiliary pump and a controller. The auxiliary pump has a low side adapted to be coupled to the hydraulic reservoir and a high side adapted to be coupled to the hydraulic circuit. The controller is electrically connectable to the auxiliary pump and is configured to turn on the auxiliary pump in response to receipt of a signal indicating that the vehicle is in a stop condition to maintain hydraulic pressurization of the hydraulic circuit of the transmission when the vehicle is in the stop condition.
